Recently, there is a growing practice among providers of pre-set a WPA password for you (or rather the data modems through a free WiFi to users). This has led to
fortunately widespread use WPA instead of WEP vulnerable to or instead of a network completely open.
Another good thing in the case of Fastweb is leaving users with the ability to change passwords at will through the portal to the remote provider. The portal is also present an algorithm for generating random passwords.
analysis of that algorithm I can confirm that the password created is really accidental.
However the idea of \u200b\u200busing a password preset different from modem to modem pushes the curious to wonder what the criteria these passwords are generated.
behind a deterministic algorithm with which we obtain the passphrase?
The situation really needs to be analyzed separately for each model of modem. The provider in question currently provides two different models of WiFi modem: a one Telsey and Pirelli.
E 'confirmed that both models Pirelli models Telsey, the answer is YES
': The default WPA password printed below each modem Fastweb can be uniquely inferred from other parameters of the modem.
To test the safety Fastweb write to your network saxdax2@gmail.com , sending the network SSID and a handshake.
The SSID alone is enough to find the wpa. The handshake is used to verify that the WPA by default has not been changed.
